I recently went on vacation to Nicaragua and Panama and I had no service at all on my Droid 2 Global. The main reason I bought this phone was because I travel a lot; I've been to Canada, Mexico and Japan with the Droid 2 Global and was able to get a roaming signal, in Central America, I had no signal at all. Why was I not able to get a signal on my phone? I'm pretty disappointed that the phone is advertised as being global ready, yet I had not signal in Central America. Any help would be useful, thanks in advance.
